In this study, the yield and yield components were studied using a conventional variety Zhongshuang 11 (ZS 11) and a hybrid variety Zhongyouza 12 (ZYZ 12) at varying plant densities.
The increase in plant density led to an initial increase in seed yield and pod numbers per unit area, followed by a decrease.
The optimal plant density was 58.5 × 104 plants ha−1 in both ZS 11 and ZYZ 12.
The further researches on physiological traits showed a rapid decrease in the green leaf area index (GLAI) and chlorophyll content and a remarkable increase in malondialdehyde content in high plant density (HPD) population than did the low plant density (LPD) population, which indicated the rapid leaf senescence.
However, HPD had higher values in terms of pod area index (PAI), pod photosynthesis, and radiation use efficiency (RUE) after peak anthesis.
A significantly higher level of dry matter accumulation and nitrogen utilization efficiency were observed, which resulted in higher yield.
HPD resulted in a rapid decrease in root morphological parameters (root length, root tips, root surface area, and root volume).
These results suggested that increasing the plant density within a certain range was a promising option for high seed yield in winter rapeseed in China.
